BERKELEY -- A 23-year-old man has been arrested after allegedly hitting two people over the head with a baseball bat outside a fraternity house Sunday, police said.

Frank Watson, of Oakland, was arrested after the early Sunday attack. Police held him on suspicion of attempted homicide, assault with a deadly weapon and a probation violation, according to Berkeley police spokeswoman Jennifer Coats.

Police say Watson arrived in a car on the 2700 block of Durant Avenue at 1:25 a.m. as two groups were fighting in a UC Berkeley fraternity house parking lot. Watson allegedly grabbed a baseball bat from the trunk of the car and hit two people over the head, causing significant injuries to each victim.

The victims were taken to a hospital to be treated for head injuries. Watson did not release any information about their condition Monday.

Watson was arrested a short time later after trying to run from police officers during a car stop near Warring and Parker streets.
